An embodiment relates to a method for operating a transmitting user equipment (TX UE) for performing sidelink communication in a wireless communication system, the method comprising the steps of: receiving, by a TX UE, a power saving (PS) signal transmitted by a base station; and on the basis that the power saving signal indicates not performing skipping during an on-duration period and the TX UE has traffic to be transmitted to a receiving UE (RX UE), transmitting the traffic in at least a part of an SL on-duration period by the TX UE.
Legal claims defining the scope of protection, as filed with the USPTO.
3. The method according to claim 1, wherein a destination RX UE scheduled to receive the traffic is indicated through a traffic indication message.
4. The method according to claim 1, wherein a bitmap and a SL power signal (PS) RNTI are mapped to (SL PS RNTI) modulo N (where N is the number of bits of a traffic indication bitmap).
5. The method according to claim 1, wherein the SL PS RNTI is allocated when the TX UE establishes PC5 RRC connection with the RX UE.
6. The method according to claim 1, wherein the traffic indication message is transmitted at a first subframe starting from the on-duration period.
7. The method according to claim 1, wherein a start point of a sidelink DRX on-duration period is configured to be identical to a start point of a Uu DRX on-duration period.
8. The method according to claim 7, wherein a SL DRX cycle and a Uu DRX cycle are configured to be identical to each other.
11. The device according to claim 9, wherein a destination RX UE scheduled to receive the traffic is indicated through a traffic indication message.
12. The device according to claim 9, wherein the UE is configured to communicate with at least one of another terminal, a terminal related to an autonomous vehicle, a base station (BS), and a network.
